Abstract
A method for grinding and polishing the runner plate of water wheel generator features use of grinding diamond cream and spray grinding diamond agent as grinding and polishing material and design of grinding disks in different types and step grinding and polishing technology. Its advantages are simple technology, less consumption of energy, short productive period, low cost and improved surface fineness increased by 2 grades.
Description
The invention belongs to a kind of abrasive polishing method in the machining.
In the prior art, the abrasive polishing method of hydraulic generator mirror plate, generally be with green silicon carbide, white hard rock as grinding-material, chromium oxide as polishing material, and carry out the substep grinding and polishing.Because the volume of runner plate is big, weight is generally several tons, adopts existing method, and the runner plate of external diameter 2.8m, an internal diameter 1.6m generally spends the time in two weeks to finish grinding and polishing at least, and fineness generally can only reach
8Become
9Reach the standard grade.In addition, this method will spend a large amount of green silicon carbides, white hard rock and chromium oxide, and will investigate the mill material with a large amount of machine oil, kerosene, and environmental pollution is also quite serious, so this method not too is suitable for the requirement of modern industry development.The useful abrasive band of external similar technology mill, but must be equipped with special equipment and abrasive band.
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of and do not need other oil (gas) filling device, technology is simple, power consumption is low, with short production cycle, cost is low and the runner plate abrasive polishing method of sanitation and hygiene.
Main points of the present invention are with the diamond paste to be grinding-material, and spray abrasive for diamond is a polishing material, and design grinding, the polishing disk of different model, carry out the technology that substep grinds, polishes.When workpiece ground, its finished surface was lubricated with machine oil and kerosene at any time, cooling, when changing dish in each step, must surface of the work be cleaned up with gasoline, absorbent cotton.
The grinding-material that the present invention adopts is a diamond paste, and its model is W

#Abrasive disk is a cast iron plate outsourcing wool felt, 3
#, 4
#With 5
#The thickness of wool felt is respectively 5mm, 10mm and 15mm.6
#Be polishing disk, the characteristics of this dish are that innermost layer is a cast iron plate, middle for wool felt, skin are pleuche, and the thickness of wool felt is generally 20mm.This abrasive polishing process is finished on vertical lathe, runner plate is flatted turn on lathe, the abrasive disk that scribbles grinding-material under the drive of runner plate and rotation, the rotating speed of abrasive disk and the rotating speed of runner plate with runner plate to contact pressure relevant, abrasive disk can be by the lathe adjustment with the pressure that contacts of runner plate.
The concrete technology of the present invention can divide following a few step to finish:
1. the bright and clean in runner plate finish turning rear surface

1.5Spray abrasive for diamond in any evenly be sprayed on the pleuche and polish, can improve the fineness and the brightness of runner plate rapidly, this moment, fineness reached
11More than.
Whole technical process generally can be finished with interior at 72 hours, and take time is relevant with the runner plate size.The rotating speed of runner plate on vertical lathe is generally 60-90 rev/min, the rotating speed of abrasive disk can by abrasive disk and runner plate contact pressure adjustment, rotating speed is generally 90-150 rev/min.
The present invention removes and is applicable to the runner plate grinding and polishing, also is applicable to the grinding and polishing on other small, annular thing and other large-scale plane.
Characteristics of the present invention and effect.
1, the surface smoothness of runner plate can guarantee at
11More than, compare with former technology, improve two more than the grade.
2, working time and production cost only are 1/3rd of former technology.
3, in the grinding and polishing process, labor intensity of operating staff alleviates greatly, and working environment is pollution-free.
Specific embodiments of the invention are as follows:
Grinding workpiece is a hydraulic generator mirror plate, and this runner plate external diameter is that 2.8m, internal diameter are 1.6m, and material is a cast steel.Grinding-material is selected W for use
